Viabilidade financeira do uso de poços artesianos na construção de edifícios em Palmas/TO

Abstract

In this research, it was obtained the survey and the analysis of eight works of vertical commercial and residential buildings, with similar constructive characteristics. The result was the determination of an average consumption index of 0.4886 cubic meters of water for each square meter of construction. At the same time, the Palmas / TO market was studied for the execution of wells with a depth of more than 70 meters. Thus, data were obtained from eight wells, generating an average flow of 11,200 liters per hour, an average depth of 123 meters, an average static level of 16 meters and an average dynamic level of 52 meters. In this way, the monthly consumption index was calculated for the peak month of the works, resulting in 0.055 cubic meters per square meter of constructed work. With the sum of the cost of construction of the theoretical well, its consumption of electric energy and environmental licensing fees, the amount of R $ 34,850.52 was obtained. When crossing the data collected and calculated, a delimitation in square meters of constructed area of 2,248.42 square meters was generated for vertical works, that is, it was concluded that, in the case of works with larger built-up areas than the one presented, it becomes economically viable the execution of deep artesian wells as an alternative to the public water supply network.
